Wylie Bay (WA 142) continues to curve round from the rock outcrop for 1.3 km to the lee of Wylie Head where it faces east. Waves decrease from about 1 m to less than 0.5 m and the beach transforms from a continuous bar with a 50 m wide surf zone to a sheltered reflective beach used to launch the boats (Fig. 4.37). In addition in the southern corner there is a large boulder just north of the southern tip of the beach, and seagrass debris often accumulated on the high tide beach. The two beaches are backed by a series of active blowouts extending up to 2 km inland, and then by vegetated Holocene parabolics dunes that reach up to 5 km inland, and then by massive vegetated Pleistocene transgressive dunes averaging 60-80 m in elevation that in places extend 35 km to the west, reaching the shores of Rossiter Bay and beyond. Many of the inner dunes were reactivated during the glacial maxima (approximately 18 000-20 000 years ago) and have a more westerly orientation together with numerous water-filled deflation hollows. The entire system covers and area of about 350 km2, and surround some of the inner granite peaks read more
